My 04 Suburban has special rear shocks with integrated airbags to level the vehicle. I ordered Monroe OEM-replacement parts for these shocks, and a new air compressor. RockAuto shipped me two different shocks, mislabeled in the box, and the compressor. I sent back the shock which was wrong, and they sent me a replacement: the same, wrong shock. When I called the fellow appologized. I decided to send back the two shocks and the compressor as RockAuto seems unable to fill the order correctly. I am now being charged return shipping for the compressor (which is useless without the two shocks) becuase I "did not want it". When I pointed out to RockAuto that the compressor is useless without the shocks, and they don't see able to send me the correct shocks, the response I received was "Well, you could source the shocks elsewhere and then use our compressor with them." I have ordered from RockAuto many times. I have always been very impressed by them. They have utterly failed me this time. Time to find a new place to order parts from.
